nonsubsampled Contourlet decomposition NSCT

I have an image (medical image) 1024*1024 I'm trying to decompose it using the NSCT toolbox but every time I run the code I got this error:

    This error was detected while a MEX-file was running. If the MEX-file
    is not an official MathWorks function, please examine its source code
    for errors. Please consult the External Interfaces Guide for information
    on debugging MEX-files.

the only mex files I'm using are the ones in the Toolbox

    nlevels = [0, 1, 3] ;        % Decomposition level
    pfilter = 'maxflat' ;              % Pyramidal filter
    dfilter = 'dmaxflat7' ;              % Directional filter

    % Nonsubsampled Contourlet decomposition
    coeffs = nsctdec( double(im), nlevels, dfilter, pfilter );
